| (54) | Digital signal recording method and apparatus and recording medium therefor |
| (57) A format for the recording of trick play signals is proposed in which trick play
segments comprising sync blocks of information of a trick play signal are recorded
in groups of p successive tracks. At least first and second trick play signals are
recorded on the record carrier. The first trick play signal is meant for reproduction
in a reproduction apparatus at a reproduction speed n1 times the recording speed with
which the trick play signals are recorded on the record carrier. The second trick
play signal is meant for reproduction in the said reproduction apparatus at a reproduction
speed n2 times the recording speed. Both trick play signals are recorded such that
upon reproduction at said speed n1 times the recording speed m1 sync blocks of information
of the first trick play signal and m1 sync blocks of the second trick play signal
are read from the record carrier during one revolution of the head drum in the reproduction
apparatus |
